The invention relates to an attachment or nally V'at opposite sides of the planter `in accessory adapted for use on agricultural spaced parallelv relation. The shoes12 may implements or machines used for the purpose be of the stub type, or may be of the rounded of planting seeds or sowing grain, or for pull type. "The shoes 12 are designed Yand such machinery which employs appuradapted for making furrows or ditches in 5g tenances or shoes for making furrows or which are depositedgrain or seeds', after ditches in which grain or seeds are deposited. which fthe furrows or ditches vare closed by In order that the benefits and advantages wheels forming parts ofthe planter. 1 The of the invention may be fully understood and shoes 12 `are rigidly maintained in their set 1o appreciated, attention iscalled to the followrelation by a cross rod 13 secured to the shoes 6.0 ing facts: Planter shoes in action will gather and arranged between the same.

In Figure 2 of the drawing, the parts are shown normally disposed. The lever 18 has a lateral proj ection or stop 26 thereon which is positioned to engage the frame 11 to limit the movement of the lever 18 in the forward direction in the shoe scraping operation. The rod 19 is curved or bent as at 27 so as to engage the tubular member 15 to limit the movement of the lever 18 rearwardly to its normal position, as shown in Figure 2. It will be apparent that as soon as the pressure of the foot on the lever 18 is Withdrawn, the spring 23 will function to return the lever 18 to its normal position and incidentally raise or elevate the Scrapers 16 through the intervention of the rod 19, arm 22 and tubular member 15.

From the foregoing it Will be app arent that undesirable material may be removed from the shoes 12 at Will. The Scrapers 16 coming in contact With the shoes 12 will loosen the material Which will utimately be removed partly by gravitation, but mostly by friction, as the planter travels over the ground. It will be obvious that the scraper attachment Will serve advantageously on grain planters and machines designed for planting potatoes and other vegetaables. It enables a better grade of Work to be achieved While saving time and expense.

Claims:

1. A planter or the like having the combination of a frame, furrow or ditch making shoes secured to said frame, a part mounted on said frame and having turning movement, Scrapers rigidly mounted on said turning part, said scrapers being positioned relatively to said shoes to scrape undesirable material from the shoes by turning said part, a lever mounted on said frame connected With said turning part and operable to cause the turning movement of said part for the stated pnrpose, yieldable means connected With said frame and lever to return the latter to a normal position and to thereby turn said part to a position to normally retain said scrapers in elevated positions, and a stop integral With the lever and engageable With said frame to limit the movement of the lever. I

2. A planter or the like lia-ving the combination of a frame, a furrovv or ditch making shoes secured to said frame, a part mounted on said frame and having turning movement, Scrapers rigidly mounted on said turning part, said scrapers being positioned relatively to said shoes to scrape undesirable material from the shoes by turning said part, a lever mounted on said frame, a rod connected with said lever and turning part to cause the turning movement of said part by the operation of the lever for the stated purpose, yieldable means connected with said frame and lever to return the latter to a normal position and to thereby turn said part to a position to normally retain said scrapers in elevated positions, said rod being engageable With said lever.
